Stuff that doesn't fit…

this is only temporary anyway, till we get a real bug tracker.

Problem getting software form Tails [SOLVED]

  • (proper) Following Tails is also very hard. I though about grabbing tails_htp. They have a git but that's not protected by SSL or SSH. Only way to safely extract something out Tails is downloading the iso, verifying the iso, unpacking squashfs (btw: "sudo unsquashfs -x -dest /home/user/tails filesystem.squashfs" and grabbing it from there. They also don't have an apt repository yet and they are also not like upstreaming all their work.
  • (anonymous) but they say git is signed, what's the problem? https://mailman.boum.org/pipermail/tails-dev/2012-June/001254.html
    • (proper) Do you know how to verify it? I haven't found out.
      • (anonymous) git tag -v; commits after the last signed tag are not to be trusted. There are tons of git tutorials and guides.
      • (proper) I was on the wrong path, understood "only the download iso is signed". "git tag -v 0.12" worked for me.
  • (proper) I'd also like to extract torsocks/libtorsocks from Tails, because they fixed the "The symbol res_query() was not found in any shared library. The error reported was: not found!" bug. Perhaps that's not necessary and we can use the Debian package, if they fixed that upstream.

[MISC] Ubuntu server 64-bit [ANSWERED]

  • (adrelanos) Any objections using Ubuntu server 64-bit as T-W's operating system? At least for private builds? What I see so far: fingerprinting issues, the exit node and mirror can guess, that someone uses aos with 64-bit instant of 32-bit. Since the streams are now separated, I see no big issue with that. Anything else? As long as we have PAE as requirement, we could also switch to 64-bit? Do all PAE-featured CPU's also support 64-bit?
  • (anonymous) I don't know. AMD64 is older than PAE. However, 32bit software runs without problems on 32bit and 64bit hosts, 64bit software no so much. Because we generally don't control what host OS people use I chose to base aos on 32bit. Vbox does support that mode for some time but I assumed that there are performance implications. Secondly 64bit software needs more RAM, we already run 3 OS (or more) on a system which eat RAM, better minimize that (KVM and other solutions improve RAM usage through page sharing or what it's called, VBox doesn't). Thirdly, according to Brad Spengler and/or PAX team amd64 is a brain dead instruction set and actually worse than x86, despite the large address space making ASLR more effective. They recommended to use grsec on x86 and I hope we can switch to a grsec kernel (wheezy has one, let's see if they maintain it).
